Swami Mukundananda
How can I be more patient and understanding with people who behave badly?
See others' struggles, change your expectations
If you expect the best and ideal behaviour from others, you get disturbed when it does not come, so change your own expectations. When you understand that each person has their own frailties, issues and difficulties, you become lenient and considerate.
If you understand that the person is a human being with their own frailties, issues and difficulties they are coping with, then you will be lenient and considerate towards them.
